About the authors
Andreas Helland has a degree in software engineering and 20 years of experience in
building products and services. He has worked both with the development side and the
infrastructure side and holds a number of Microsoft certifications across both skill sets.
This background led him to become an early adopter of Azure and the cloud.
After building up his knowledge working in the telecommunications industry, he switched
to consulting, and he currently works as an architect for Capgemini, where he assists
customers with utilizing the cloud in the best ways possible. He specializes in Azure
Active Directory and works closely with the Identity teams at Microsoft, both in testing
new services and providing feedback based on learnings from the field.
I want to thank Ed for roping me in on this project – of course there’s time
available to write a book! Thanks to Vince and Jeffrey for bringing in their
content and perspectives – it would have been a thin (and less exciting)
book if it was only me doing the writing. I enjoyed working with you!
Thanks to Packt for making sure there’s been plenty to do when we have to
spend most of our time at home – books are the perfect companion activity
for that.
Vincent Maverick Durano works as a software engineer/architect at an R&D company
based in Minnesota. His jobs include designing software, building products and services
that impact the lives of people. He’s passionate about learning new technologies, tackling
challenges, and sharing his expertise through writing articles and answering forums. He
has authored several books and has over 15 years of software engineering experience.
He has contributed to OSS projects and founded AutoWrapper and ApiBoilerPlate. He
is a 10-time Microsoft MVP, 5-time C# Corner MVP, 3-time CodeProject MVP, and
a contributor to various online technical communities. He’s from the Philippines and
married to Michelle and has three wonderful children – Vianne, Vynn, and Vjor.
I want to thank Ed for bringing me on board to be part of this book and to
my other co-authors: Andreas and Jeff – you guys are awesome! It was fun
and a great experience working with you. To Kinnari, Francy, and the Packt
team – thank you!

Special thanks to Kinnari, Francy, and the Packt Team for the drive and
support; Andreas for his leadership and vision; Vince for his dedication and
measured advice; and Ed for bringing the authors together, his wit, and his
contributions to the ASP.NET community.
Ed Price is a senior program manager in engineering at Microsoft, with an MBA in
technology management. He has run Microsoft customer feedback programs for Azure

development scenarios). He is the co-author of four books, including Learn to Program
with Small Basic and Hands-On Microservices with C# and .NET Core 3, Third Edition
(from Packt).
What do you do when the world is quarantined in 2020 from COVID-
19? You write a book! I want to thank the ASP.NET community and my
amazing partners on this book: Andreas for being our technical leader,
Vince for joining us last (only to show us up by providing the most content),
and Jeffrey for being our rock and anchor (and for writing amazing run-on
sentences in his biography).
